1 1998-06-10 Theodore Ts'o <tytso@rsts-11.mit.edu>
3 * pass1.c, problem.h: Change blkcnt_t to be e2_blkcnt_t to avoid
4 collision with LFS API.
6 * pass1.c (e2fsck_pass1): Fix bug so that ext2_max_sizes is
8 (e2fsck_pass1): Don't allow the the boot loader inode to
9 be a directory (clear the inode mode field if so).
11 1998-05-07 Theodore Ts'o <tytso@rsts-11.mit.edu>
13 * unix.c (PRS): Added new option -C, which causes e2fsck to print
14 progress updates so that callers can keep track of the
15 completion progress of e2fsck. Designed for use by
16 progress, except for -C 0, which prints a spinning report
17 which may be useful for some users.
19 * pass5.c (e2fsck_pass5): Use a finer-grained progress reporting
20 scheme (useful for larger filesystems).
22 * e2fsck.h: Add progress_fd and progress_pos, for use by the Unix
23 progress reporting functions.
25 1998-04-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
27 * pass1.c (process_inode_cmp): Use EXT2_QSORT_TYPE to define the
28 appropriate return type for comparison functions for qsort.
30 * e2fsck.h: Add #ifdef protection for unistd.h
32 * super.c: Remove header files already included by e2fsck.h
34 1998-04-26 Theodore Ts'o <tytso@rsts-11.mit.edu>
36 * dirinfo.c (e2fsck_add_dir_info): Update function to pass the old
37 size of the memory to be resized to ext2fs_resize_mem().
39 1998-03-30 Theodore Ts'o <tytso@rsts-11.mit.edu>
41 * Makefile.in: Change to use new installation directory variables
42 convention. Fix uninstall rules to take $(DESTDIR) into
43 account. Remove cat8dir from the installdirs target,
44 since modern man package don't necessarily put the cat
45 directory in /usr/man/cat?.
47 1998-03-29 Theodore Ts'o <tytso@rsts-11.mit.edu>
49 * super.c, e2fsck.h: Always declare e2fsck_get_device_size() as an
50 extern in e2fsck.h to prevent -Wall warnings.
52 * pass4.c (e2fsck_pass4): Remove unused variable 'j'.
54 1998-03-28 Theodore Ts'o <tytso@rsts-11.mit.edu>
56 * super.c (check_super_block): Fix broken superblock sanity check
57 when calculating blocks_per_group if s_log_frag_size !=
58 s_log_block_size. Since we don't support fragments, this
59 isn't a bug deal, but it's good to get it fixed.
61 1998-03-23 Theodore Ts'o <tytso@rsts-11.mit.edu>
63 * unix.c: Fix bug in check of feature set, to make sure we can
64 really fix this filesystem.
66 * problem.h: Make blkcount type to be of type blkcnt_t. Make the
67 num field be a 64 bit type. Add the problem code
68 PR_1_FEATURE_LARGE_FILES
70 * problem.c: Add table entry for the problem code
71 PR_1_FEATURE_LARGE_FILES.
73 * pass1.c (e2fsck_pass1): A non-zero i_dir_acl field is only
74 a problem for directory inodes. (Since it is also
75 i_size_high now.) If there are no large_files, then
76 clear the LARGE_FLAG feature flag. If there are
77 large_files, but the LARGE_FLAG feature flag is not set,
78 complain and offer to fix it.
79 (check_blocks): Add support to deal with non-directory
80 inodes that have i_size_high set (i.e., large_files).
81 Don't give an error if a directory has preallocated
82 blocks, to support the DIR_PREALLOC feature.
83 (process_block, process_bad_block): The blockcnt variable
84 is a type of blkcnt_t, for conversion to the new
87 * pass2.c (process_bad_inode): A non-zero i_dir_acl field is only
88 a problem for directory inodes. (Since it is also
91 * message.c (expand_inode_expression): Print a 64-bits of the
92 inode size for non-directory inodes. (Directory inodes
93 can only use a 32-bit directory acl size, since
94 i_size_high is shared with i_dir_acl.) Add sanity check
95 so that trying to print out the directory acl on a
96 non-directory inode will print zero.
97 (expand_percent_expression): %B and %N, which print
98 pctx->blkcount and pctx->num, can now be 64 bit
99 variables. Print them using the "%lld" format if
100 EXT2_NO_64_TYPE is not defined.
102 * e2fsck.h: Add the large_flagsfield to the e2fsck context.
104 * e2fsck.c (e2fsck_reset_context): Clear the large_flags
107 Sun Mar 8 23:08:08 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
109 * pass3.c (fix_dotdot_proc):
110 * pass2.c (check_dot, check_dotdot, check_name, check_dir_block):
111 * message.c (expand_dirent_expression): Mask off the high eight
112 bits of the directory entry's name_len field, so that it
113 can be used for other purposes.
115 Fri Feb 27 00:01:39 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
117 * e2fsck.c (e2fsck_run): Since E2F_FLAG_SIGNAL_MASK doesn't
118 include EXT2_FLAG_RESTART anymore, we need to adjust this
119 routine so that it *does* return in the case of it seeing
122 * pass1.c (e2fsck_pass1): ext2_get_next_inode() may call the group
123 done callback function, which may set context abort
124 flags. So we need to test the context abort flags after
125 we call ext2_get_next_inode().
126 (process_inodes): If we abort due out of process_inodes,
127 do a clean exit by breaking out of the for loop instead of
130 * e2fsck.h (E2F_FLAG_SIGNAL_MASK): EXT2_FLAG_RESTART shouldn't be
131 considered a SIGNAL mask (i.e., requiring an immediate
132 abort of processing to restart). FLAG_RESTART just means
133 that we want to restart once pass 1 is complete.
135 Tue Feb 24 15:19:40 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
137 * Change the progress function to return an integer; if returns 1,
138 then the progress function is expected to have set the
139 e2fsck context flag signalling a user abort, and the
140 caller should also initiate a user abort.
142 Tue Feb 17 19:03:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
144 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Don't call
145 end_problem_latch() unless there was actually a problem
146 latched. Simplifies semantics of the latch processing.
148 Mon Feb 16 17:31:44 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
150 * e2fsck.h: Add new field, priv_data to the e2fsck context
151 structure. It should be used by callers of the e2fsck
152 functions only, and not by anything in e2fsck itself.
154 Mon Feb 7 17:31:04 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
156 * super.c: Instead of call ext2fs_get_device_size(), define and call
157 e2fsck_get_device_size(). (This function may be stubbed
158 out in special versions of e2fsck.)
160 * pass3.c, pass4.c: Remove extra calls to the progress function
163 * mke2fs.8.in: Update man page to note that the format of the bad
164 block file is the same as the one generated by badblocks.
166 Sun Feb 1 07:57:14 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
168 * dirinfo.c, e2fsck.c: Don't include com_err.h; it isn't needed.
170 * e2fsck.h: Include <time.h> since it is needed
172 * super.c: If EXT2_SKIP_UUID is defined, then skip the UUID
175 Tue Jan 20 15:37:01 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
177 * unix.c (main): In the case where the filesystem revision is too
178 high, print the message about the superblock possibly
181 * e2fsck.8.in: Add expanded comments about how the -b option
184 Sat Jan 17 13:02:16 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
186 * e2fsck.h: If EXT2_FLAT_INCLUDES is defined, then assume all of
187 the ext2-specific header files are in a flat directory.
189 * dirinfo.c, ehandler.c, pass1.c, pass1b.c, pass2.c, pass5.c,
190 super.c, swapfs.c, unix.c: Explicitly cast all assignments
191 from void * to be compatible with C++.
193 Tue Jan 6 11:30:24 1998 Theodore Ts'o <tytso@rsts-11.mit.edu>
195 * unix.c (sync_disk): Remove sync_disk and calls to that function,
196 since ext2fs_close() now takes care of this.
198 Mon Dec 29 14:45:42 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
200 * pass1.c, pass1b.c, pass2.c, pass3.c, swapfs, badblocks.c,
201 ehandler.c, unix.c: Change use of private to be priv_data,
202 to avoid C++ reserved name clash.
204 Fri Nov 28 09:30:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
206 * dirinfo.c (e2fsck_add_dir_info): Use ext2fs_get_num_dirs instead
207 of e2fsck_get_num_dirs, which has been removed.
209 Tue Nov 25 15:54:35 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
211 * Makefile.in (PROGS): Remove @EXTRA_PROGS@, since we don't want
212 to compile and install flushb.
214 Mon Nov 24 06:48:00 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
216 * pass1.c (e2fsck_pass1_check_device_inode): For now, only check
217 to make sure the extra i_blocks in a device are cleared if
218 the immutable flag is set.
220 * util.c (print_resource_track): Fix typo which caused the
221 time/resource tracking to print "Pass 1 :" instead of
224 Thu Nov 20 16:02:23 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
226 * pass3.c (expand_directory): Fix bug which could cause core dump
227 when expanding the directory, and the bitmaps hadn't yet
228 been read in. Also, only use ext2fs_write_dir_block when
229 writing a directory block, not when writing out a fresh
232 Wed Nov 19 16:15:44 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
234 * pass1.c (process_bad_block): Fix bug where first_block wasn't
235 getting incremented, which caused user to get a
236 "Programming error?" warning if there was a bad block in a
237 non-primary superblock/group_descriptor. Also fixed
238 another bug so that ext2fs_bg_has_super() is consulted, to
239 avoid problems when using a filesystem with the
240 sparse_groups option set and there are bad blocks at the
241 beginning of a group which doesn't have a superblock.
243 Thu Nov 6 16:10:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
245 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c: Add calls to the
246 progress indicator function.
248 * pass1.c (scan_callback): Add call to the progress feedback
249 function (if it exists).
251 Tue Nov 4 09:45:36 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
253 * super.c (check_super_block): Skip the device size check if the
254 get_device_size returns EXT2_EXT_UNIMPLEMENTED.
256 * iscan.c (main): Don't use fatal_error() anymore.
258 * pass1b.c, swapfs.c, badblocks.c: Set E2F_FLAG_ABORT instead of
259 calling fatal_error(0).
261 * problem.c, pass3.c (PR_3_ROOT_NOT_DIR_ABORT,
262 PR_3_NO_ROOT_INODE_ABORT): New problem codes.
264 * problem.c, pass2.c (PR_2_SPLIT_DOT): New problem code.
266 * problem.c, pass1.c (PR_1_SUPPRESS_MESSAGES): New problem code.
268 * problemP.h: New file which separates out the private fix_problem
271 * util.c, dirinfo.c, pass1.c, pass1b.c, pass2.c, pass5.c, super.c,
272 swapfs.c util.c: allocate_memory() now takes a e2fsck
273 context as its first argument, and rename it to be
274 e2fsck_allocate_memory().
276 Mon Nov 3 14:35:29 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
278 * unix.c (main): Add a special case check for the error code EROFS
279 and display an appropriate error message for this case.
281 * [lots of files]: Change ext2fs_read_inode, ext2fs_write_inode
282 to take the e2fsck context as their first argument.
283 Change dir_info.c routines to take an e2fsck_context,
284 renamed them to start with e2fsck_ to avoid namespace
285 issues, and changed them to store the directory
286 information inside the e2fsck context.
287 Added e2fsck_run() which calls all of the e2fsck passes in
288 the correct order, and which handles the return of abort
289 codes. Added abort processing, both via setjmp/longjmp
290 and via flags in the e2fsck context. Use a flag in the
291 e2fsck context instead of the restart_e2fsck global
292 variable. Change uses of free and malloc to
293 ext2fs_free_mem and ext2fs_get_mem.
295 Fri Oct 31 01:12:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
297 * pass1.c, pass3.c: Rename new error codes to _ET_ in them for
300 Sat Oct 25 00:10:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
302 * pass3.c (get_lost_and_found): Check error return of
303 EXT2_FILE_NOT_FOUND instead of ENOTDIR
305 * pass1.c (pass1_check_directory): Return EXT2_NO_DIRECTORY
308 Fri Oct 24 00:12:39 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
310 * unix.c (PRS): Make the variable which getopt returns into be
311 an int, so that it won't lose on platforms where char is
314 * pass1b.c (clone_file): Fix bug in error reporting in the case
315 where cs.errcode is non-zero.
317 Sun Oct 19 21:12:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
319 * pass*.c, super.c, unix.c, util.c, e2fsck.h: Place #ifdef
320 RESOURCE_TRACK around code which uses init_resource_track
321 and print_resource_track. (Not all systems have timeval)
323 * super.c: Remove excess #includes which are not necessary.
325 * e2fsck.h: Add #ifdef's for HAVE_SYS_TYPES_H and HAVE_SYS_TIME_H
327 Fri Oct 3 13:40:03 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
329 * pass*.c, super.c: Massive changes to avoid using printf and
330 com_err routines. All diagnostic messages are now routed
331 through the fix_problem interface.
333 Sat Sep 6 17:13:28 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
335 * pass2.c (check_dir_block): Check for duplicate '.' and '..'

341 Tue Sep 2 09:04:51 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
343 * problem.c: Added new problem codes for some of the
344 superblock corruption checks, and for the pass header
345 messages. ("Pass 1: xxxxx")
347 * util.c (print_resource_track): Now takes a description
350 Mon Aug 25 10:23:13 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
352 * super.c, unix.c, e2fsck.c: New files to separate out the
353 operating-specific operations out from e2fsck.c.
354 e2fsck.c now contains the global e2fsck context management
355 routines, and super.c contains the "pass 0" initial
356 validation of the superblock and global block group
359 * pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
360 (nearly) all global variables and moved them to the e2fsck
363 * problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
364 PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS,
365 PR_0_BLOCKS_PER_GROUP, PR_0_FIRST_DATA_BLOCK
367 Thu Aug 14 10:55:21 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
369 * message.c: Add compression for the word "Illegal"
371 * problem.c: Added entries for PR_2_BAD_CHAR_DEV and
374 Wed Aug 13 09:55:57 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
376 * pass1.c (pass1, check_device_inode), pass2.c
377 (process_bad_inode): Use a more stringent test for a valid
380 Sun Aug 10 18:58:02 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
382 * e2fsck.c (check_mount): Add stronger warning message about the
383 perils of running e2fsck on a mounted filesystem.
385 Tue Jun 17 01:33:20 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
387 * Release of E2fsprogs 1.11
389 Thu Jun 12 00:25:31 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
391 * pass1.c (mark_table_blocks): Mark the superblock and group
392 descriptor blocks first, so that any conflicts between
393 these and the bitmap or inode table blocks is noticed.
395 * problem.c: Fix message printed out when a block or inode bitmap
396 conflicts with other fs data, has the correct group number
399 Tue Jun 10 12:07:37 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
401 * pass2.c (pass2): Check the error return from ext2fs_dblist_iterate.
403 Thu May 8 22:45:27 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
405 * e2fsck.8.in: Fix minor typos and grammer oops found by Bill
406 Hawes (whawes@star.net).
408 * badblocks.c (read_bad_blocks_file): Pass the blocksize to the
409 bad blocks command so that all of the filesystem gets
410 tested in the case where the blocksize 2048 or 4096.
412 Thu Apr 24 12:16:42 1997 Theodre Ts'o <tytso@localhost.mit.edu>
414 * Release of E2fsprogs version 1.10
416 Mon Apr 21 22:43:08 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
418 * pass1b.c (pass1b): While scanning for inodes, simply skip inodes
419 where ext2fs_get_next_inode returns the
420 EXT2_ET_BAD_BLOCK_IN_INODE_TABLE error.
422 Thu Apr 17 12:23:38 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
424 * Release of E2fsprogs version 1.09
426 Fri Apr 11 18:56:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
428 * Release of E2fsprogs version 1.08
430 Thu Apr 10 13:51:16 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
432 * pass1b.c (clone_file_block): If we clone a directory, we need to
433 update the dblist entry so that we check (and correct) the
434 right directory block.
436 Sun Apr 6 09:13:12 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
438 * pass1.c (process_block): Don't clear blocks references to
439 filesystem metadata; let pass 1B handle this case.
441 * problem.c, problem.h: Add new problem, PR_1B_SHARE_METADATA.
443 * pass1b.c (pass1d): Deal with a block which is shared with
446 * e2fsck.h: Make block_illegal_map be a global variable
448 Sat Apr 5 11:51:58 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
450 * e2fsck.c, pass1.c (mark_table_blocks): Support the sparse_super
452 (get_backup_sb): New function which attempts to obtain the
453 correct backup superblock (if possible).
455 Fri Apr 4 10:46:26 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
457 * e2fsck.c (main): Check the version of the library, and warn if
458 the library is out of date; this happens generally due to
459 users who manually install e2fsprogs.
461 * pass1.c (pass1_get_blocks): If the passed in inode number for
462 get_blocks isn't what we're expecting pass back
463 EXT2_ET_CALLBACK_NOT_HANDLED.
465 Wed Mar 12 13:32:05 1997 Theodore Y. Ts'o <tytso@mit.edu>
467 * Release of E2fsprogs version 1.07
469 Tue Mar 11 10:31:47 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
471 * icount.c: New file which implements an inode count abstraction.
472 This significantly reduces amount of memory needed to
473 check really large filesystems.
475 * pass1.c, pass2.c, pass3.c, pass4.c: Modified to use the icount
478 Fri Mar 7 08:28:55 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
480 * dirinfo.c (dir_info_iter): New function which allows iteration
481 over the directories in the dir_info map.
483 * pass3.c (pass3, check_directory): Speed up pass 3 by iterating
484 over all directories in the dir_info structure, instead of
485 iterating all inodes looking for directories, and then
486 looking up the directories using get_dir_info().
488 Sat Feb 1 11:33:43 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
490 * pass1.c (pass1, process_block):
491 * pass2.c (pass2): Use the ext2_dblist abstraction instead of
492 manual code to manage the directory block list information.
494 * pass1.c (check_blocks), pass1b.c (pass1b), pass2.c
495 (deallocate_inode): Call the ext2 library routine
496 ext2_inode_has_valid_blocks() instead of
497 inode_has_valid_blocks().
499 * swapfs.c (swap_inodes): Add check so that we don't try to call
500 swap_inode_blocks unless the inode has valid blocks.
501 (Otherwise a long fast symlink might cause
502 swap_inode_blocks to erroneously get called.)
504 Wed Jan 22 14:42:53 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
506 * problem.c, problem.h: Added entries for PR_2_DOT_NULL_TERM and
507 PR_2_DOT_DOT_NULL_TERM.
509 * pass2.c (check_dot, check_dot_dot): Make sure the new . and
510 .. entries are null-terminated, since the 2.0 kernel
511 requires this (for no good reason).
513 Mon Jan 20 20:05:11 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
515 * pass1.c (pass1): Set the EXT2_SF_SKIP_MISSING_ITABLE flag so
516 that we can recover from missing inode tables.
518 * dirinfo.c (get_dir_info): If there are no directories in the
519 dir_info abstraction, don't core dump (because dir_info is
522 * e2fsck.c (main): Don't try using the backup superblocks if there
524 (check_super_block): If there are illegal inode table or
525 bitmaps, set the filesystem as being in error.
527 Wed Jan 15 11:32:01 1997 Theodore Ts'o <tytso@rsts-11.mit.edu>
529 * pass2.c (check_dir_block): Added check to make sure that rec_len
530 is a a multiple of 4 (so that the directory entries are
533 Sat Dec 28 12:16:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
535 * Makefile.in (uninstall): Uninstall all programs in the PROGS
537 (PROGS): Don't build and install the extend program by
541 Sat Dec 7 16:41:02 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
543 * pass1.c (process_inodes): Make sure the stashed_ino variable is
544 saved and restored as well.
545 (pass1): For fast sym links, skip the check_blocks
546 processing step altogether.
548 Mon Dec 2 09:28:24 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
550 * problem.c, message.c: New files, to completely refurbish how
551 filesystem problems are reported to the user. The
552 diagnostic messages are now encoded out in an easily
553 customizable, extensible format. The messages printed out
554 in preen mode are all on one line, and contain the device
557 Fri Nov 29 20:26:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
559 * swapfs.c (swap_inodes): When swapping a filesystem, ignore
562 * pass1.c (pass1): Ignore missing inode table errors during the
563 scan, and just skip past those inodes.
565 * pass3.c (check_root): Remove root_ino argument, and assume that
566 the root inode must be EXT2_ROOT_INO. Move responsibility
567 of setting the parent of the root inode in the directory
568 inode structure to pass2().
570 * pass2.c (check_dir_block): Don't allow links to the root
573 * dirinfo.c (add_dir_info): Remove last argument to add_dir_info,
574 since the inode is no longer used.
576 Tue Oct 15 00:06:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
578 * e2fsck.c (main): If the superblock magic number is wrong, or the
579 block group fails a sanity check, then automatically
580 restart trying to use the backup superblocks.
582 * pass1.c (mark_table_blocks): Make the inode tables ahead of
583 everything else; in the case where a bitmap block overlays
584 the inode table, the inode table should take precedence.
586 * pass2.c (maybe_clear_entry): Make the deleted/unused error
587 message fit on one line, since the error can happen during
588 a preen pass. (We eventually need to revamp the whole
589 e2fsck error reporting and prompting system, but that's a
590 job for another day.)
592 Mon Oct 14 22:29:49 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
594 * e2fsck.c (main): Read in the list badblocks into fs->badblocks
595 for the benefit of the inode scan functions.
597 * pass1.c (pass1): If ext2fs_get_next_inode() returns an error
598 indicating that an inode is in a bad block, mark that
599 inode as being used, as well as in the inode "bb" map.
601 * pass2.c (maybe_clear_entry): New function which generalizes the
602 error cases when a directory entry needs to be cleared.
603 (check_dir_block): If an inode is in the "bb" map, offer
604 to clear the directory entry, since the inode is in a bad
607 * pass4.c (pass4): If an inode is marked as used, but is is marked
608 in the "bb" map, don't process it as a disconnected inode.
610 Tue Oct 8 02:02:03 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
612 * Release of E2fsprogs version 1.06
614 Mon Oct 7 00:45:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
616 * e2fsck.c (main): Print out the version number of the shared
617 library when using the -V option.
619 * swapfs.c (swap_filesys): Change EXT2_SWAP to EXT2_FLAG_SWAP for
622 * e2fsck.c (main): By setting EXT2_FLAG_MASTER_SB_ONLY, only write
623 out the backup superblocks when we know we have a valid
626 Tue Oct 1 22:00:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
628 * util.c (preenhalt): Make it explicit on preenhalt that running
629 e2fsck manually means without the -a or -p flag.
631 Fri Sep 27 14:41:08 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
633 * pass1.c (pass1): Add support for the EXT2_BOOT_LOADER inode.
634 (Linux/FT actually sets the mode bits, so we have to
635 handle it specially.)
637 * e2fsck.c (check_if_skip): Print a message if the filesystem is
638 just dirty, so that the user knows that it's about to be
639 checked (since this will take a while).
641 Mon Sep 16 17:00:01 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
643 * pass4.c: If a disconnected inode is zero-length, prompt to
644 delete it instead of connecting it to lost+found.
646 Thu Sep 12 15:23:07 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
648 * Release of E2fsprogs version 1.05
650 Fri Aug 30 20:24:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
652 * pass4.c (pass4): If the user refuses to connect an unattached
653 inode to lost+found, don't try to set i_links_count. This
654 is bad, since if the user says yes, the inode will be
655 marked as unused, which is not necessarily the right
656 thing, especially since the rest of the cleanup doesn't
659 * pass2.c (deallocate_inode): Set inode_link_info[ino] when
660 dellocating an inode. (Not strictly necessary, but...)
662 * pass4.c (pass4): Add "bonehead" explanation to the "programming
665 Tue Aug 27 11:26:32 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
667 * e2fsck.c (PRS,main): Added new options -s and -S. -s will
668 byte-swap the filesystem so that it is normalized. -S
669 will byte-swap the filesystem regardless of its current
672 * swapfs.c: New file, which will byte-swap a filesystem.
674 Tue Aug 20 09:41:37 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
676 * pass1.c (pass1): Change handling on files with non-zero dtime
677 and non-zero i_link_count; before we treated them as
678 deleted file per botched ext2 0.3c kernel behavior. We
679 now clear dtime instead.
681 Mon Aug 19 23:33:57 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
683 * e2fsck.c (main): If e2fsck sets the clean bit, even if
684 nothing else is changed, make sure FSCK_NONDESTRUCT is
685 set (since after all having the filesystem set to
686 invalid is an error. :-)
688 Fri Aug 9 10:25:13 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
690 * pass1.c (process_block): Make sure that meta data doesn't get
691 accidentally set in the dir_blocks array (which could
692 happen in some error condtions).
695 * pass2.c (process_bad_inode): Check for fragments in a
696 OS-independent fashion.
698 Thu Aug 8 15:20:54 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
700 * e2fsck.c (check_if_skip): Close the filesystem when skipping the
701 cleanup for the filesystem.
703 Mon Jul 22 22:03:28 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
705 * e2fsck.c: Improve corrupt_msg, so that it's less confusing.
707 Thu May 16 11:12:30 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
709 * Release of E2fsprogs version 1.04
711 Wed May 15 21:41:29 1996 Theodore Ts'o <tytso@rsts-11.mit.edu>
713 * e2fsck.c (relocate_hint): Issue a hint that the user may wish to
714 try "e2fsck -b 8193" before allowing e2fsck to relocate
717 * Makefile.in (e2fsck): Build e2fsck statically or dynamically
718 depending on the option to configure. Added targets for
719 e2fsck.static and e2fsck.shared for people who want to
720 build a static or shared variant manually.
722 Wed Mar 27 00:33:40 1996 <tytso@rsts-11.mit.edu>
724 * Release of E2fsprogs version 1.03
726 Tue Mar 26 12:03:42 1996 <tytso@rsts-11.mit.edu>
728 * e2fsck.c (show_stats): Don't use floating point to display
729 percentage of non-contiguous files, as different libc
730 handle result truncation differently, and this causes the
731 test suite to bomb out depending on which libc you are
734 * util.c (allocate_memory): Fix error message to omit extraneous
737 Tue Mar 5 03:50:40 1996 <tytso@rsts-11.mit.edu>
740 * pass2.c (check_dir_block):
741 * pass1.c (pass1): Add support for dynamic first inode revision.
743 Wed Feb 14 16:27:30 1996 <tytso@rsts-11.mit.edu>
745 * pass3.c (check_root): Fix spelling typo
747 Mon Feb 5 22:30:30 1996 <tytso@rsts-11.mit.edu>
749 * e2fsck.c (check_super_block): If the superblock fails certain
750 internal consistency checks, exit with a fatal error after
751 printing the "superblock is corrupt message".
753 Wed Jan 31 11:06:08 1996 <tytso@rsts-11.mit.edu>
755 * Release of E2fsprogs version 1.02
757 Wed Dec 15 21:24:26 1996 <tytso@rsts-11.mit.edu>
759 * pass1.c (process_block): Check to see if a file is "fragmented".
760 i.e., non-contiguous. Note that any file which is larger
761 than the block group is guaranteed to be non-contiguous.
762 We may want to use a different hueristic for deciding
763 whether or not a file is "fragmented".
765 * e2fsck.c (show_stats): Print statistics of how many
766 non-contiguous files are on the system.
768 Fri Dec 15 19:19:47 1995 <tytso@rsts-11.mit.edu>
770 * badblocks.c (read_bad_blocks_file, test_disk): Fold
771 functionality of test_disk() (which runs badblocks) into
772 read_bad_blocks_file(); test_disk() now calls
773 read_bad_blocks_file() with a NULL bad_blocks_file
776 Mon Nov 20 18:30:10 1995 <tytso@rsts-11.mit.edu>
778 * e2fsck.c (check_mount): Use #if defined(__linux__) instead of
779 #if defined(linux). The latter won't work if we're
782 Mon Oct 30 20:31:17 1995 <tytso@rsts-11.mit.edu>
784 * e2fsck.c (check_mount): For Linux systems, the check to see if
785 the root is mounted read-only has to be done for all
786 filesystems, not just for the root filesystem, due to the
787 way that some /etc/rc scripts are set up.
789 Thu Oct 26 12:05:30 1995 <tytso@rsts-11.mit.edu>
791 * Makefile.in (install): Strip programs when they are installed.
792 (e2fsck): Build e2fsck statically.
794 Wed Oct 25 21:18:16 1995 <tytso@rsts-11.mit.edu>
796 * util.c (preenhalt): Preenhalt now takes an argument, which is an
797 ext2fs_filsys; this allows it to set the EXT2_ERROR_FS
798 flag in the superblock in cases where preenhalt is called.
799 All calls to preenhalt() were changed to either
800 preenhalt(fs) or preenhalt(NULL) in a few cases where the
801 fs pointer was not available. (Most notable, for block
804 Mon Sep 4 21:41:03 1995 Remy Card <card@bbj>
807 util.c: Include <sys/time.h> before <sys/resource.h>. BSD needs it.
809 Mon Sep 4 10:14:49 1995 <tytso@rsts-11.mit.edu>
811 * e2fsck.c (show_stats): Show statistics about how many inodes
812 have indirect, doubly indirect, and triply indirect
813 blocks. Allow up to 8 digits for statistics, instead of
814 merely 6, so things look pretty for large filesystems.
816 * pass1.c (pass1): Keep statistics about indirect, doubly
817 indirect, and triply indirect blocks.
819 * pass1.c (unwind_pass1): Clear the above statistics when unwinding
822 Fri Aug 18 15:17:10 1995 Theodore Y. Ts'o <tytso@dcl>
824 * util.c, ehandler.c: Move #include of <sys/resource.h> after
825 #include of "e2fsck.h", since sys/resource.h may depend on
826 sys/time.h, which is #included in e2fsck.h.
828 Thu Aug 17 22:33:37 1995 <tytso@rsts-11.mit.edu>
830 * e2fsck.c (check_mount): Use the new ext2fs_check_if_mounted()
831 function to determine if the device is mounted.
833 * e2fsck.c (main): Add better error messages if ext2fs_open()
836 Wed Aug 16 16:25:02 1995 <tytso@rsts-11.mit.edu>
838 * pass1.c (check_blocks): If we're clearing a directory, clear
839 pb.is_dir so we don't do the following check of making
840 sure the directory size matches; this is pointless, since
841 we've already cleared the inode.
843 Fri Aug 11 09:08:54 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
845 * pass1.c (bad_primary_block): New function, called by
846 process_bad_block, which explains the facts of life to the
847 user when a block in the primary superblock or primary
848 group descriptors is bad.
850 * pass2.c (check_dot): Handle the case where the first directory
851 entry is used, but not ".".
853 * pass2.c (check_dotdot): Handle the case where the second directory
854 entry is used, but is not "..".
856 Thu Aug 10 10:05:10 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
858 * e2fsck.c (check_super_block): Get the size of the physical
859 device and if it is smaller than the reported size of the
860 filesystem, report an error.
862 Sat Aug 12 03:39:18 1995 Remy Card <card@bbj>
864 * e2fsck.c (check_if_skip): Print the number of allocated files and
865 blocks on clean filesystems.
867 Fri Aug 11 14:15:36 1995 Remy Card <card@bbj>
869 * e2fsck.8: Updated date and version number.
871 Thu Aug 10 14:26:01 1995 Remy Card <card@bbj>
873 * pass1.c (check_blocks): Check that directory size matches *exactly*
874 the count of allocated blocks.
876 Wed Aug 9 21:21:24 1995 Theodore Y. Ts'o <tytso@dcl>
878 * pass1b.c (pass1d): Free the shared[] array when we're done with
879 it to avoid a memory leak.
881 * pass1.c (unwind_pass1): Use ext2fs_free_block_bitmap to free the
884 * pass2.c (process_bad_inode): When clearing the inode, make sure
885 the pathname is freed, to prevent a memory leak.
887 * pass5.c (check_inode_bitmaps): Free free_array and dir_array
888 when we're finished with them.
889 (check_block_bitmaps): Free free_array when we're finished
892 * Makefile.in (e2fsck, flushb): Use $(LD) instead of $(CC) when
893 linking the executable.
895 * pass2.c (process_bad_inode): Even on OS's that don't support the
896 fragment fields, make sure the Linux equivalent fields are
897 set to zero. If an OS wants to reuse these fields, which
898 is probably a bad idea (although we may get desperate in
899 the future) this code will have to be changed.
901 * pass1.c (dir_block_cmp): If the block numbers are equal, compare
902 on the inode field, and then blockcnt field. This is just
903 to keep the ordering of dir_blocks the same on all
904 platforms when there are more than on missing directory
905 blocks, which are indicated directories with holes, which
906 are indicated with the block number being set to zero.
908 Sun Aug 6 15:40:58 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
910 * pass1.c (check_blocks, process_block): check_blocks() modified
911 to call the ext2fs_block_iterate() with BLOCK_FLAG_HOLE if
912 the inode is a directory. process_block() now checks to
913 see if a directory has a "hole", or missing block. If so,
914 this fact is recorded in the directory block list so that
915 the problem can be resolved in pass #2.
917 * pass2.c (allocate_dir_block): Added allocate_dir_block() to
918 allocate new blocks for directories with "holes". Called
919 out of check_dir_block if a block in the directory block
922 * pass3.c (get_lost_and_found): Move location of free(block) to
923 prevent possible memory leak.
925 Sat Aug 5 12:42:22 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
927 * pass2.c (check_dir_block): Use a automatic, fixed-saize array
928 instead of alloca() --- alloca is not portable! Check to
929 make sure the filename is not longer than EXT2_NAME_LEN,
930 and offer to fix it by truncating it, since it should
933 * e2fsck.c (PRS): Use malloc() instead of alloca() --- alloca() is
934 not portable!! In any case putenv() in some systems must
935 take a static character array or malloc()'ed memory;
936 passing memory allocated using alloca() to putenv() is not
939 * pass2.c (check_dot, check_dotdot): Use malloc() instead of
940 alloca() --- alloca() is not portable!!!
942 Tue Jul 18 20:04:02 1995 <tytso@rsx-11.mit.edu>
945 * pass3.c (check_root, get_lost_and_found):
946 * pass2.c (check_dir_block): Use ext2fs_{read,write}_dir_block
947 to read/write the directory block.
949 Mon Jul 17 04:00:56 1995 <tytso@rsx-11.mit.edu>
951 * util.c (ask_yn): Apply patch supplied by Peter A. Zaitcev to
952 make sure VMIN and VTIME are set correct.
954 Fri Jul 14 19:26:29 1995 <tytso@rsx-11.mit.edu>
956 * pass1.c (mark_block_used): Change to be an inline function.
957 Assume that the block validity checks are already done,
958 and use the fast variant of the bitmap functions.
960 Thu Jul 13 08:10:55 1995 <tytso@rsx-11.mit.edu>
962 * pass5.c (check_block_bitmaps, check_inode_bitmaps): Check the
963 bounds of the bitmaps in advance, and then use the fast
964 variant of e2fs_test_{block,inode}_bitmap.
966 * pass1.c (mark_block_used): Use ext2_fast_mark_block_bitmap since
967 the bounds checking has already been done earlier.
969 Wed Jul 12 02:22:46 1995 <tytso@rsx-11.mit.edu>
971 * pass1.c (pass1): Allocate and free the block_illegal_map, which
972 is used for shortcut processing in process_block.
973 (mark_table_blocks): Initialize block_illegal_map with the
975 (describe_illegal_block): New helper function that
976 describes why a block is illegal.
977 (process_block): Use block_illegal_map as a shortcut
978 to determine whether a block is bad. Use
979 describe_illegal_block to print out why the block is illegal.
981 Mon Jun 12 19:11:06 1995 Theodore Y. Ts'o (tytso@dcl)
983 * flushb.c: Don't include <linux/fs.h> if it doesn't exist.
985 * scantest.c: Don't include <linux/fs.h>, <getopt.h>, or
986 <mntent.h> if they don't exist. (Mostly so that "make
989 * pass1.c, pass1b.c, pass3.c, badblocks.c: Include <errno.h> (if
992 * e2fsck.c, scantest.c: Don't include <getopt.h> if it doesn't
995 Mon Jun 12 08:37:49 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
997 * pass2.c (process_bad_inode, check_for_zero_long,
998 check_for_zero_char): Change long to u32, and char to u8.
1000 Sun Jun 11 15:05:57 1995 Theodore Y. Ts'o <tytso@lurch.mit.edu>
1002 * util.c (inode_has_valid_blocks):
1003 * pass2.c (process_bad_inode):
1004 * pass1.c (pass1, check_blocks, pass1_check_directory): Use
1005 LINUX_S_IS* instead of S_IS*.
1007 * e2fsck.h: Don't #include <sys/stat.h>
1009 * flushb.c (main): Add #ifdef BLKFLSBUF around ioctl. (Although
1010 this program is pretty much useless if BLKFLSBUF isn't
1013 * e2fsck.c, badblocks.c: Add #include <errno.h>, since errno is
1016 Thu Jun 8 12:31:19 1995 Miles Bader <miles@churchy.gnu.ai.mit.edu>
1018 * pass2.c (check_dot, check_dotdot, check_dir_block): Use alloca
1019 to allocate space for file names instead of using fixed size buffers.
1020 (process_bad_inode): Only check inode frag fields if
1021 HAVE_EXT2_FRAGS is defined (by configure).
1022 * pass1.c (pass1): Only check the inode frag fields if
1023 HAVE_EXT2_FRAGS is defined (by configure).
1025 * e2fsck.c (check_mount): Only check for a mounted filesystem if
1026 HAVE_MNTENT_H is defined (by configure).
1027 (PRS): Use alloca to allocate the new path string, instead of
1028 having a fixed size buffer (which was the wrong size anyway).
1029 (PRS): Only support the -F (flush) option if the BLKFLSBUF ioctl
1032 * e2fsck.h: Only include <linux/fs.h> if HAVE_LINUX_FS_H is
1033 defined (by configure).
1035 * Makefile.in: Rewritten to conform to GNU coding standards and
1036 support separate compilation directories.
1038 Thu Apr 6 15:04:36 1995 Remy Card <card@bbj.ibp.fr>
1040 * pass1.c (pass1): Test the mode in reserved inodes (must be zero).
1042 Sat Mar 11 13:12:16 1995 Theodore Y. Ts'o <tytso@localhost>
1044 * pass1.c (unwind_pass1): Clear the file type statistics counter
1045 when pass 1 needs to be restarted from scratch.
1047 * pass1.c (handle_fs_bad_blocks): Fix bug where bitmap blocks were
1048 being reallocated to blocks in the next block group,
1049 instead of the current block grup.
1051 * pass1.c (pass1, check_blocks): Set inode_link_info[ino] whenever
1052 inode.i_links_count is set.
1054 Tue Feb 14 01:38:04 1995 Theodore Y. Ts'o (tytso@rt-11)
1056 * pass1.c (process_block): Add checks for if the block is
1057 trepassing on a superblock or group descriptor table.

1061 * main.c (corrupt_msg): Extend the message which is printed out
1062 when the superblock is corrupt, to include the suggestion
1063 of using the -b option to specify an alternate superblock.
1065 Thu Nov 24 09:29:58 1994 Theodore Y. Ts'o (tytso@rt-11)
1067 * badblocks.c (read_bad_blocks_file): If we are adding or
1068 replacing bad blocks in the bad blocks inode, sanity check
1069 the bad block inode first, and clear out any illegal blocks.
1071 * pass2.c (check_name): Don't bomb out if the attempt to get the
1072 pathname of the containing directory returns an error; the
1073 directory may be too badly damaged to expect that
1074 ext2fs_get_pathname will always succeed. Use "???" if the
1075 pathname can't be obtained (it's only for a printf to the
1078 The name of the containing directory and the bad filename
1079 were incorrectly interchanged in the user message. Fixed.
1081 * pass2.c (check_name, check_dir_block): Use a common static
1082 string for the unknown pathname.
1084 Mon Nov 7 22:30:54 1994 Remy Card <card@bbj>
1086 * Fixed lots of printf formats to make sure that block and inode
1087 numbers are printed as unsigned integers.
1089 Mon Oct 24 14:10:46 1994 (tytso@rsx-11)
1091 * pass5.c (check_block_end): Fix calculation of how the last block
1092 in the block bitmap should be calculated.
1094 Wed Sep 7 10:01:13 1994 (tytso@rsx-11)
1096 * pass1b.c (pass1_dupblocks): Fix declaration of dup_inode_map to
1097 be an ext2fs_inode_bitmap, and free it properly.
1100 * e2fsck.c (main): Folded in Remy Card's changes to add a revision
1101 level to the superblock.
1103 Wed Aug 17 22:00:20 1994 Remy Card (card@bbj)
1105 * e2fsck.c (usage): Fixed bogus usage message.
1107 Wed Aug 17 11:21:45 1994 Theodore Y. Ts'o (tytso@rt-11)
1109 * pass1.c (process_bad_block): Fixed bug so that blocks in the
1110 backup superblocks and group descriptors are handled gracefully.
